picture control +opencv打开摄像头（set parent方法）

在Oninit（）

里添加

cv::namedWindow("view", cv::WINDOW_NORMAL);
	HWND hWnd = (HWND)cvGetWindowHandle("view");
	HWND hParent = ::GetParent(hWnd);
	::SetParent(hWnd, GetDlgItem(IDC_STATIC)->m_hWnd);
	::ShowWindow(hParent, SW_HIDE);
	cv::resizeWindow("view", 803, 617);//和我的picture control大小一致

在button里添加

cv::VideoCapture capture;
	cv::Mat myImagine;
	capture.open(0);
	CRect rect;
	GetDlgItem(IDC_STATIC)->GetClientRect(&rect);

	for (;;)
	{
		capture >> myImagine;
		cv::imshow("view", myImagine);
		cvWaitKey(10);
	}
